I’ve a string like this,

-p User/Dob -f MM/dd/yyyy -flag somevalue

How can I extract values like below using Regex,

p = "User/Dob"
f = "MM/dd/yyyy"
flag = somevalue

This is what I’ve tried so far,

public static string MERGE_ARGS_REGEX = @"-[a-z]";

var arguments = Regex.Matches(metadata, MERGE_ARGS_REGEX)
    .Select(x => x.Value.Replace("\", ""))
    .ToList();

var argumentValues = Regex.Split(metadata, MERGE_ARGS_REGEX)
    .Where(x => !string.IsNullOrEmpty(x))
    .Select(x => x.Trim())
    .ToList();

I’m getting the values array in the argument argumentValues. I think the code can be improved. Can you someone please advise how to do it better.
